As to the spacers on the transfercase thing NOBODY KNOWS the correct answer. I did the swap last year and asked everyone I could find but no one can tell me. I'm leaning toward the "tilt the driveline thing" due to the added length of the T18 and adaptor it makes it easier on your driveshaft so I did it. Clearance did not matter. I had the body lift also.
If you do find the right answer email me and let me know.
